Abstract: 
fac-Tris(2-phenylpyridine) iridium [Ir(ppy)(3)] has been investigated by means of soft desorption/ionization induced by neutral SO2 clusters in combination with mass spectrometry. Desorption of intact Ir(ppy)(3 )was observed. Further analysis of the isotopic pattern revealed two forms of ionization, either by uptake of a proton or by electron abstraction. The relative contribution of the two processes depends on measurement time and H2O partial pressure, as well as preparation scheme and surface morphology of the samples.
